• Hide certain contact's profile pictures-While you can conceal your stories from particular contacts on WhatsApp, this functionality does not extend to your profile picture. Changing your profile image is the equivalent of announcing to your contacts that you are using WhatsApp.
• Sending Messages to Unknown Contacts Requires Permission- WhatsApp could also add a new feature that prevents someone from messaging you without first making a request. Currently, anyone who has obtained your phone number can send you a message regardless of whether or not they are on your contact list.
• Support for two accounts-Two SIM cards are supported by the majority of Android handsets and current iPhones. However, WhatsApp only allows you to use one account per device. This prevents me from having a private account for close friends and a public account for everyone else.
